The Influence of Shear on Mixing across Density Interfaces.
Abstract
The paper discussed critically experimental observations of mixing processes across density interfaces in laboratory experiments and inferences that have been made and can be made from these observations. It is shown that the drag coefficient in flow of a stratified fluid over a rough surface is independent of the Richardson number (or density jump across the interface or inversion) and depends only on the ratio of the roughness length to the depth of the homogeneous layer. This has obvious implications for problems of parameterizing the momentum flux near the ground in the atmosphere. (Modified author abstract)
